I know that disabled status all too well. Have had several of this days recently myself. Down time is tough.
I read another post of yours where you asked someone for recommendations for supplements. The response you received is one I hope you Google before proceeding to take it!
Here's a cut + paste example of what has been mainstreamed to public media recently:
"New research from the University of Missouri-Columbia indicates the popular dietary supplement nicotinamide riboside (NR) may promote an increased risk of cancer, and may even cause cancer to metastasize / spread to the brain.
Prior research had suggested that nicotinamide riboside, a source of vitamin B3, may benefit cardiovascular, metabolic, and neurological health. NR supplements have claimed to provide extra energy, increased physical performances, and even anti-aging effects. This latest study serves as a strong motivator to leave this supplement on the shelf."

You can find the actual published study if you look and want to read it

Wishing you a prompt recovery.
